Specification of Letters Patent.

Patented Aug. 8, 1911.

Application filed November 30, 1909. Serial No. 530,654.

To alt whom it may concern:

Be it known thatL'Eocnn S. BECK, a citie States, a resident of T eichlers, in the county of Northampton, in the State of Pennsylvania, have invented or discovered new and useful Improvements in Electric-Circuit-Opening Devices, which are more fully described and claimed in the annexed specification. 1

Thisinvention relates to improvements circuit breaking devices and the leading object of the invention is to provide a device wherein an electrolyte and a air of electrodes are employed, one of said electrodes being removable from the electrolyte and the other being secured therein, and an improved: connection between the movable electrode and a manually operated switch, whereby the removable electrode will be withdrawn from the electrolyte by operating the manual switch.

Another object of the invention is to provide an improved cell for the electrodes, the removable electrode may be "ith the above and other obj ectsin view pitll "invention relates to certain construct ons, combinations and arrangements of parts clearly described in the- 1 following specification and clearly illustrated 'in the accompanying drawing, in which the figure is a side elevation with parts shown in section,

Referring to the accompanying drawings 1 denotes amanual circuit breaker which is supported on a standard or board 2. A second support 3 is secured by the clamping device 3* to the first support or board 2, and said second support 3 has a bracket 4 secured thereto, which serves as a support for the outer cell 5. The outer cell 5 contains an insulating oil 8 and an inner cell 7 which is formed of rubber or other insulating materialand is held in spaced relation to said outer cell 5 by means of insulating plugs 11 located bet-weenthe bottoms of the inner-and plugs 11 located bet-ween the upper edges of the outer and inner cells. The inner cell contains an electrolyte and an insulating oil 9' which vfloats on the electrolyte 9.

A negative electrode 10, which is formed with a U-shaped lower end is submerged in the electrolyte 9 and its upper end is connected to the conductor 20. A positive elec-.

trode 6 is submerged in the electrolyte 9 and connects with a depending rod 12 which is pivoted at its upper end to the horizontal lever 13 which is pivotally mounted at 14 to the upstanding arm 14, carried by the support or board 2. The upstanding arm 14 has secured thereto a spring 15 which has an upturned outer end to engage the lever 13 and which spring is adapted to counteract the weight of the electrode 6 and the connecting rod 12. The other end of the lever 13 is connected to an insulating member 16 which in turn is connected to a depending link 17, which has its lower end pivoted to a second link 18, the outer end of which link is pivoted at 18 to the lever 1 of the manual circuit breaker 1. The upstanding arm 14 is connected with a conductor 19 which in turn connects with a bolt 19 that passes through the support 2 and which supports on its outer end a contact member 19 which is adapted to engage a contact member 1 carried bythe lever 1*.

W hen the lever l is moved in an are upwardly in the direction of the arrow shown in the drawing the depending link 17 will be moved downwardly and theelectrode 6 will be withdrawn from the electrolyte 9 and consequently the circuit will be broken. A carbon or an aluminum plate is preferred for the positive electrode and the depending connecting rod 12 should be (if aluminum to lighten the weightt-hereof. Normally the current does notflow through the electrodes 6 and 10 and only flowsthrough said electrodes when the manual circuit breaker has opened so that the normalpath of the current has been interrupted, the electrodes then temporarily receive the load or the current until the positive electrode 6 has been withdrawn.

Having described my invention I claim: In a circuit breaker, a cell having an electrolyte, a stationary negative electrode therein, a positive electrode removable from said electrolyte, an insulating-oil disposed in said cell over the electrolyte, a support, a lever nwunted for pivntal movement on said suparecl switch, and electrical connections forsmcl electrodes and swltch. 10
